Description

TECHNICAL FIELD

[0001] The present application relates to a screw machine, in particular to an air suction type integrated installation screw feeder. BACKGROUND

[0002] Screw is a tool that uses the physical and mathematical principles of the inclined surface of the object and the friction force to tighten the machine parts gradually. Screw feeder, also known as screw arrangement machine, is a small automatic device that arranges screws in a row for the purpose of improving work efficiency, and is widely used in electronic industry.

[0003] At present, there are various types of screws needed to be locked on a single product. When locking different positions of the same product by the equipment, the corresponding screw feeder may need to be frequently replaced.

[0004] In order to solve the speed of changing the screw feeder, the volume of the screw feeder needs to be as small as possible, and it is installed in the equipment to provide the equipment with different screw feeding and locking. SUMMARY

[0005] In order to solve the above problems of the prior art, the present application provides an air suction type integrated installation screw feeder, which realizes miniaturization of the machine and can be used for integrated installation.

[0006] In order to achieve the above purpose, the present application provides the following technical scheme:

[0007] An air suction type integrated installation screw feeder, which comprises a base, a chute chamber, a vibrating seat, a track, a distribution mechanism and a track pressing plate, the chute chamber is installed at the rear end of the base; the vibrating seat is fixed at the middle position of the base and is located in front of the chute chamber, a track is arranged on the vibrating seat and the rear end of the track extends into the chute chamber; the distribution mechanism is installed at the front side of the base and is connected with the front end of the track, the track pressing plate is fixed on the distribution mechanism and is located directly above the track;

[0008] The chute chamber comprises a roller fixing plate mechanism fixed on the base, a roller installed on the right side of the roller fixing plate mechanism, a roller motor mechanism, a brush mechanism, a brush motor mechanism and a U-shaped groove installed on the left side of the roller fixing plate mechanism, a lack of material sensor fixed on the bottom of the U-shaped groove, a front plate mechanism fixed on the front end of the U-shaped groove, and the brush mechanism is installed above the front plate mechanism; the brush mechanism is driven by the brush motor mechanism to control the frequency and running time of the brush swing, the roller is provided with 8 scooping pieces to improve the feeding efficiency; and the both ends of the scooping piece are closed to prevent the screws from sliding off from both sides during feeding.

[0009] A pair of transmission sensors are installed on the vibrating seat to detect the screws on the track to prevent the screws from piling up on the track due to continuous feeding of the drum, thereby causing the screws to jam when running on the track.

[0010] The drum includes a drum body and a drum back baffle, eight scooping pieces are arranged at the middle position of the drum body, and baffle plates are arranged on both sides to shield the screws to prevent the screws from sliding off.

[0011] An electromagnetic lock is installed at the rear end of the tank chamber to lock the cover of the screw feeder bin.

[0012] Compared with the prior art, the beneficial effects of the present application are:

[0013] 1. The existing screw feeder drum installation position adopts a rear-mounted type, and the diameter directly affects the size of the entire machine. When the track is installed, the rear end of the track must be spaced apart from the drum to allow the screws not falling into the track to fall from the rear, so the feeding efficiency is not high during feeding. And when encountering special size screws, the rear end of the track may be jammed with the drum, affecting the track vibration feeding. One side of the drum is open, and the screws are easy to slide off the scooping piece during drum feeding, causing feeding difficulty. In the present application, the drum is installed on the side, so that the width of the feeder is not affected by the diameter of the drum, thereby reducing the width of the entire machine. And the drum is provided with eight scooping pieces to improve the feeding efficiency; and the scooping pieces are closed at both ends, so that the screws are not easy to slide off during feeding.

[0014] 2. In the prior art, no sensor is installed on the track to detect the number of screws on the track. In the case of excessive screws on the track, the screws are easy to stack on the track, causing the screws to jam or run abnormally on the track. In the present application, a sensor is installed on the vibrating seat C to detect the screws on the track to prevent the screws from piling up on the track due to continuous feeding of the drum, thereby causing the screws to jam when running on the track.

[0015] 3. In the prior art, the drum feeding and brush swinging are driven by one motor. A transmission shaft is installed at the shaft end of the drum motor, a small gear is installed at the end of the transmission shaft to drive the drum to rotate, a cam is installed at the other end of the transmission shaft, and the cam pushes the brush driving plate to drive the brush to swing when rotating. The feeding and the brush are linked to run, which is easy to cause the screws to jam on the track, and it is not easy to remove the screws in abnormal posture. In the present application, the brush is driven by an independent motor mechanism, and the frequency and running time of the brush swinging can be controlled independently. The effect of removing the screws in abnormal posture on the track can be significantly improved. BRIEF DESCRIPTION OF DRAWINGS

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0029] Please refer to Figures 1-6 ;

[0030] Example 1​​​

[0031] In the embodiment of the present application, a suction type integrated installation screw feeder comprises a shell, a base A, a chute chamber B, a vibrating seat C, a track D, a distribution mechanism E and a track pressing plate F. The position relationship is that the chute chamber B is installed on the base A and located at the rear end of the base A. The vibrating seat C is also installed on the base A and located at the middle position of the base A and in front of the chute chamber B. The track D is installed on the vibrating seat C and the rear end of the track extends into the chute chamber. The distribution mechanism E is installed in front of the base A and is connected with the front end of the track. The track pressing plate F is fixed on the distribution mechanism E and located directly above the track D.

[0032] The chute chamber B comprises a roller motor mechanism B-1, a brush motor mechanism B-2, a front plate mechanism B-3, a U-shaped groove B-4, a roller fixing plate mechanism B-5, a brush mechanism B-6, a roller B-7, a roller transmission gear B-8, an electromagnetic lock B-9 and a material shortage sensor B-10. The roller B-7 is installed on the right side of the roller fixing plate mechanism B-5. The roller motor mechanism B-1, the brush motor mechanism B-2, the front plate mechanism B-3, the U-shaped groove B-4 and the brush mechanism B-6 are all installed on the left side of the roller fixing plate mechanism B-5. The roller motor mechanism B-1 and the brush motor mechanism B-2 are installed below the U-shaped groove B-4, and the material shortage sensor B-10 is installed at the bottom of the U-shaped groove B-4. The front plate mechanism B-3 is installed at the front end of the roller fixing plate mechanism B-5 and located in front of the U-shaped groove B-4. The brush mechanism B-6 is installed above the front plate mechanism B-3.

[0033] The material shortage sensor B-10 is installed at the lower end of the U-shaped groove in the chute chamber B and is used to detect the remaining amount of screws in the chute chamber. When the remaining amount of screws is less than the sensing range, the machine outputs a material shortage signal to remind the operator to replenish the material in time. This avoids the interruption of production caused by the shortage of screws and thus reduces the production efficiency.

[0034] An electromagnetic lock B-9 is installed at the rear end of the chute chamber and is used to lock the upper cover of the screw feeder bin. When multiple screw machines are integrated, the upper cover of the bin can be opened after the material bar code is scanned by a code scanning gun. This prevents the operator from opening the upper cover of the bin at will when multiple machines are integrated, which may cause the material to be put into the wrong screw feeder and affect normal production.

[0035] The roller B-7 is installed on the side, so that the width of the feeder is not affected by the diameter of the roller, and the width of the entire machine is reduced.

[0036] Eight scooping pieces are arranged in the roller to improve the loading efficiency, and the two ends of the scooping pieces are closed to prevent the screws from sliding off from the two sides during the loading process.

[0037] The 8 scooping pieces B-7-1-1 arranged on the drum body B-7-1 are placed in the middle position after the drum rear baffle B-7-2 is combined with the drum body B-7-1, and the baffle shields the screws on both sides to prevent the screws from sliding off.

[0038] A pair of transmission sensors C-1 are installed on the vibration seat C for detecting the screws on the track D. In the case that the amount of screws on the track does not reach the sensor detection position, the drum starts feeding; after the amount of screws on the track reaches the sensor detection position, the drum stops feeding. This method can prevent the screws from piling up too much on the track due to the continuous feeding of the drum, thereby causing the screws to be stuck on the track when running.

[0039] The brush mechanism B-6 is driven by the brush motor mechanism B-2, and the frequency and running time of the brush swing are controlled separately, which can significantly improve the effect of removing abnormal posture screws on the track.

[0040] The distribution mechanism E adopts a groove wheel mechanism for positioning in a mechanical manner. The 4-degree positioning is accurate, the running deviation is small, and the distribution stability and positioning accuracy are relatively high. Figure 9 As shown in the drawings, the rotating motor E-6 drives the dial E-1 to rotate, and the dial E-1 drives the cross groove wheel E-2 to rotate. The rotating shaft E-3 penetrates the cross groove wheel E-2 and is riveted thereto. The rotating shaft E-3 synchronously rotates with the cross groove wheel E-2. The upper end of the rotating shaft E-3 is installed with the distribution disc E-4, which also synchronously rotates. The disc device plate E-5 and the distribution disc E-4 are installed in the same plane and concentric with the outer circle of the distribution disc E-4.

[0041] When the dial E-1 rotates by 180 degrees, the semicircle E-1-1 engages with the semicircle E-2-1 arranged on the cross groove wheel E-2. If the sensor detects a screw at the same time, the rotation is stopped, and the two are in engagement. At this time, the distribution disc E-4 cannot be rotated at will.

[0042] The screw enters the 4 openings E-4-1 arranged on the distribution disc E-4, which can only accommodate 1 screw, from the front end of the track. After rotation, the screw reaches the designated position

[0043] The working principle of the present application is as follows:

[0044] The screw is placed in the chute chamber B and slides down to the drum B-7 through the U-shaped groove B-4. The drum is internally provided with 8 C-shaped scooping pieces. The drum motor mechanism B-1 drives the drum B-7 to rotate, and the screws falling into the drum are transported to the above of the track rear guide piece D-1 by the scooping pieces.

[0045] The screw falls from the upper end to the guide D-1 on the right side of the track, is vibrated through the track D, and is screened by sliding from the guide to the track. While the screw is vibrated forward on the track, the brush motor mechanism B-2 drives the brush to swing, and the screw in abnormal posture on the track is excluded to the outside of the track.

[0046] After the screw in normal posture is arranged on the track, it is vibrated to the front end of the track, reaches the front end of the track, and reaches the front end of the track. The disc on the distribution mechanism is provided with four notches capable of accommodating one screw, the screw enters the notch of the disc from the track, the disc rotates while conveying the screw, the sensor of the distribution mechanism senses that the screw reaches the taking point, and the disc stops conveying, and waits for taking.

[0047] Experiments show that the application has compact and small structure, the overall width of the machine is smaller than the smallest size machine in the existing industry, and can be used for integrated installation. Each functional mechanism is independently controlled by a motor, the parameters of each motor are adjusted to achieve stable feeding effect. The digital control interface is convenient for function setting operation, and can display the number of screws used. The lack of material signal and electromagnetic lock are provided to remind the operator to add material and prevent the operator from adding material incorrectly. The modular design is convenient for assembly and maintenance.

[0048] For those skilled in the art, it is obvious that the application is not limited to the details of the above exemplary embodiments, and the application can be realized in other specific forms without departing from the spirit or essential characteristics of the application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0049] In addition, it should be understood that although the present specification is described in terms of embodiments, each embodiment does not contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments that those skilled in the art can understand.
